Unrealscript Vector Invert function

Question

Could I please get an example of the correct syntax for calling the

Invert ( out vector X, out vector Y, out vector Z )

function

Answer 1

While I couldn't find and examples of that function specifically, we can look at the out parameter modifier to get an idea of how this function might work.

In the example:

Function Clamp(Out Int Value, Int Min, Int Max) {   
    if( Value < Min)
      Value = Min;
    else if( Value > Max)
      Value = Max; 
}

And it's usage:

Clamp(Health, 0, 100);

We see that for the out parameter, we need to pass in variable that's been defined already (similar to other languages that have an out parameter modifier). Based off that, I would assume the correct syntax for the Invert function would be something like:

var Vector xVec;
var Vector yVec;
var Vector zVec;

//set vectors to something to be inverted

Invert ( xVec, yVec, zVec );

Where a Vector is defined as:

struct Vector
{
    var float X;
    var float Y;
    var float Z;
};
